 one core, ``intel_pstate`` assigns performance-based priorities to CPUs.  Namely,
 the priority of a given CPU reflects its highest HWP performance level which
 causes the CPU scheduler to generally prefer more performant CPUs, so the less
-performant CPUs are used when the other ones are fully loaded.  However, SMT

+performant CPUs are used when the other ones are fully loaded.  SMT siblings
+(that is, logical CPUs sharing one physical core) are given the same priority.
+The scheduler can pull tasks from lower-priority cores and place them on any
+sibling.  Since the scheduler spreads tasks among physical cores, tasks will be
+placed on the SMT siblings of physical cores only after all physical cores are
+busy.
 
 This approach maximizes performance in the majority of cases, but unfortunately
 it also leads to excessive energy usage in some important scenarios, like video
